MULTIPLE-SOCKET nnan.

Application filed November 14,1919.

To all whom it may concern:

Be it known that ,1, FREDERICK K. LAW- nnncna citizen of the United States residin at (lhica go, in the county of (look and 'btate of Illinois, have invented a certain new and useful Improvement in Multiple- Socket Heads, of which the following is a specification.

My invention relates to wrenches and is particularly useful as a rim wrench tor the wheels of motor vehicles. The object ot the invention is to provide a multiple socket head whichmay be used in ditl'erent positions with a single turning tool oifbrzlcc, and yet is itself so formed that after the nut has been started or loosened,it at- .iords an advantageous handle which the operator may grasp to further unscrew he nut after it has been loosened. In applying nuts, conversely, the device constitutes both a complete wrench and handle so long as the nut does not require too much torque,

after which a separate turning .tool may be multiple socket head so constructed as to coiiperate with either a socket form or stud form of wrenching tool. Another object oi the invention is to so construct the device that thetorce of the sepa rate turning ,tool. when one is used, will be applied to a point in closeproximity to the point where the socket applies its power to the nut. Still another object isto. so designthe device that it may combine strength with lightness of weight.

I obtain my objects by tl-leihflillk'iliflillil illustrated. in the accompanying drawings in which- Figure l is a side view the ,device, one of the sockets being shown in axial section.

Fig. 2 is an edge view of the parts shown in F ig. 1, certain portions being broken. away to reveal the parts within.

Specification of Letters Patent.

F {his a sectional view taken on the line l-d, 2.

.F g. 5. a perspective view showing the usual and preterred socket form of wrenching tool in distinction to the stud form shown in Fig. 6.

Ifig. 6 is a slde vlewofthe stud form of acting headlnstead of thesocket form shown in the otherfigures.

Like numerals denote .like parts throughout the several views. i i i In the form shown in Figs. 1 to 4: inclusive the device has three ,.acting .heads in i the form oi. sockets 1., 2,. and 3, "all of different sizes, thus enablingthe device to accommodate itselfito nuts or bolts of at least three different sizes. Atits inner end each socket has another socket 4, 4L, dallthelatter being of the same size bothinternally and externally and therefore all adapted to gage the same size turning tool. ,To take fullest advantage of my. in i iition the sockets l are so formed externally th t, they fit into a turning tool the socket whereof is of a different sizetro n any of the ,sockets 1, 2 or 3. The result is that, including f the turning tool, the operator is furnished with :lour different sizes ofsockets. y

in the presen instance these three acting heads or socketsl, 2, ,3 are arranged with their axes all lyingin the same plane, 120 apart, and radiating. from a coni non center, and they are held in this position by a frame or spider which, according to the special design shown, is formed in two like parts 8,. 8. One of theseparts is shown in perspective in Fig. By preference these halt spiders are otsheet metal and are spot welded, riveted or otherwise rigidly fastened to the socket members: The halt spiders engage opposite sides of the socket member's far enough from the inner end to afford adequate bearing surface. for the SOCliGllF) of theturni'ng tool. "lhey are cut away at the central portion 8" whereby a considerable space is formed to accommodate the acting head of the turning tool. Consequently it may be said that the turning tool passes through the spider in reaching the socket member which it is to engage.

As above indicated, the turning tool may be also oi the stub type 6 so as to enter inside of the sockets 4L. A turning tool of this latter type is indicated in Fig. 6.

Operation: By inspecting; Fig. 1 it will be evident that when socket 2, for example, is

in engagement with a nut, the sockets 1 and 3 range themselves in such manner as to form a very convenient handle by which the device may be grasped and rotated. In fact. the two branches temporarily out of engagement with the nut form such a good handle that the operator may, without much effort, exert so much torque that in many cases no other turning tool will be required. But when a high degree of torqueis required the operator employs. a supplemental turning 'tool in the form of a brace or similar device.

When such turning tool'is required the acting end of it is .passed through the body of the spider,- and its acting head is made to engage the inner end of the very member which is in engagement with the nut.

quently the power of the turning tool will be applied at a point close to the nut. This has at leasttwo advantages: First, it enf ables the operator to more easily and certainly keep the socket in engagement with the nut, and second, it gives the tool greater strength in proportionto the strength and thlCkHGSS'Of the metal employed. in other words, the strength of the metal of the socket member is moreefiiciently utilized by applying the power of the turning tool at a point close to the nut than it" the power were applied at a distance, or if the power were applied to the spider instead of to the acting socket member.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:

i "1. A wrenchin tool havin a body and three branches terminating in acting heads fadauted to engage an object to be turned.

and aturning tool longitudinally insertible into said body for attachment and longn tudinally retractable for ready detachment and removal, the axis of the turning tool being'in line with the axis of the temporarily acting head and the axes of the heads all lying in the same plane and radiating from a'common center and arranged one hundred and twenty degrees apart whereby 'when the turning tool is withdrawn, the two adapted to engage the acting heads at a point contiguous to the point of application of power of said acting heads.

A wrenching tool having three separate acting heads arranged with their axes in the same plane, radiating from a common center and approximately at an angle of 120 degrees apart, the inner end of each acting head being adapted to be directly engaged by a turning tool. and a spider for holding said acting heads in the position specified, said spider being hollow and having openings in line with the axes of the respective acting heads for accommodatin the turning tool.

at. In combination, a turning tool and a wrenching tool having three socket members arranged with their axes in the same plane approximately 120 degrees apart. the inner end of each of said socket members being adapted to be engaged by said turning tool. and a frame for holding said socket members in the position specified, said frame having openings in line with the axe of the respective socket members for permitting the turning tool to directly engage the inner end of the socket members.

5. The combination with a turning tool oi a vrenching tool having three aetin members arranged with their axes in the same plane approximately 120 degrees apart and radiating from a common center, each acting member being socketed at the outer end tor the reception oi a nut and socketcd at the inner end for the reception of the end of the turning tool, and a frame for holding said acting members in the position speciied, said frame having openings in line with the axes oi? the respective socket meml ers for permitting the turning tool to enter the inner socketed end of said acting members.

6. A wrenching tool having three socket members having sockets of dilterent sizes and arranged with their axes all in the same plane, approximately 120 degrees apart. the inner ends the socket; members being of the same size externally and of such size as to fit into a socket different in size trom any one of the socket members, and a spider for holding the socket members in the position specified, said spider having an opening in line with the axis of each of the socket members whereby each socket member may be directly engaged by a socketed turning tool.

In witness whereof. I have hereunto -'Hliscribed my name.

FREDERICK K. LAXVRENCE.
